Ford Blaster COP 99-04 4.6L/5.4L 4V DOHC, 8-Pack

Features

The housing and
installation of our Ford Blaster Coil-on-Plugs are the same as the factory, but
that's where the similarity ends. Inside the MSD red housing, engineers spec'd
better material to assemble the primary and secondary windings. The
Coil-on-Plug design puts the spark energy right out of the coil and across the
plug gap to improve the combustion and output of the
engine.
